SIDEWINDER 4 SENSORLESS ESC ONLY

While the all new SIDEWINDER 4™ builds upon Castle’s most popular platform, the SIDEWINDER 1:10 SCALE SERIES, it is the first of its kind to run Castle’s newest technology, CRYO-DRIVE™. CRYO-DRIVE™ combines technology from cutting-edge hardware and software advancements to increase thermal performance. COOLER TEMPS mean LONGER RUNS and MORE POWER in your SIDEWINDER 4 setup.

PROUDLY DESIGNED AND MANUFACTURED IN OLATHE, KANSAS, the NEW SIDEWINDER 4 is backed by Castle Creations’ 1-year warranty and unparalleled ‘make-it-right’ customer support.

*Not intended for operation while submerged in liquid. If unit is operated in wet conditions, rinse with fresh water to remove dirt or corrosives, then fully dry unit.

**Brushed motors are recommended for rock crawlers (vehicles traveling 3-5mph.) Brushless motors are fine for use with rock racing. If your vehicle is going to be in a bound up situation, very slowly traversing rocks and obstacles, you are running a rock crawler. If you are constantly traveling at 5mph or higher, you have a rock racer.

Now with Cryo-Drive!
Cryo-Drive technology is the result of Castle Creations' software and electrical engineers putting their heads together to improve the thermal performance of the well-known Sidewinder 3 electronic speed control. Castle has developed new software that minimizes the amount of time the ESC's electrical components spend generating heat by optimally controlling which components are being used while driving the motor. This is happening thousands of times per second, which greatly reduces the rate at which the Sidewinder 4 heats up. Overall, the Sidewinder 4 generates heat much slower than previous versions.

This software breakthrough has been coupled with a completely re-designed case. A great deal of time was spent studying fluid dynamics simulations in order to optimize the airflow through the case. Improving the airflow into and out of the case, allows the cooling fan to become more effective. In order to take full advantage of the improved airflow efficiencies, a 44% larger, higher flowrate 30mm fan was selected. The improved case coupled with the 30mm fan significantly increases the Sidewinder 4's ability to remove heat from critical components, such as MOSFETs and capacitors.

By reducing the rate at which the Sidewinder 4 heats up and removing heat more efficiently, Cryo-Drive takes thermal performance to a whole new level. The Sidewinder 4 allows users to push beyond the limits of previous generation Sidewinders by handling higher gear ratios in heavier vehicles with longer runs.

*Although Sidewinder 4 is waterproof, it is not intended for operation while completely submerged in liquid. They can corrode when exposed to corrosive materials, such as salt water. Always rinse the ESC with clean water after exposure to corrosives or dirt. While the controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind.

Application Guidelines:

The Sidewinder 4 is a versatile ESC that can be used in a wide variety of applications. it can be paired with any of our 14xx series 4-pole brushless motors; it can also be used in a rock crawling application with a brushed motor down to a 19 turn.Please refer to our Gearing Chart for recommended motor, battery and gearing for some of the more popular vehicles on the market.

Not all LiPos are created equal, and surge ratings should never be used to determine a pack’s suitability for a brushless application. Use the CONTINUOUS C rating only. Brushless setups frequently hit 100+ amps in peaks. We strongly suggest using 5,000 mAh or larger LiPo cells with a discharge rating of at least 30C (or high quality 25C batteries such as Traxxas® Power Cells®). Our experience suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.

I got 1 to put into my 2wd slash, paired with a 3800kv castle motor, the esc and motor work great together. The disappointment came in when I realized the fixed 5V BEC my servo and radio require at least 6v so my steering was sluggish and had to add on an external BEC to get the 6V to my servo. Unlike the SCT sidewinder it was replacing.
